WELL-AUGER.

Specification of Letters Patent. Patented Sept. 25, 1917.

Application filed April 11, 1917. Serial N0. 161,227.

To all whom it may concern:

Be it known that l, CLAUDE D. STILwnLL, a citizen of the United States, residing at Hamar, in the county of Eddy, State of North Dakota, have invented certain new -and useful Improvements in Tell-Angers;

and I do hereby declare the following to bc a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in well angers.

T he primary object of the invention is to provide a well auger with a cutting element which is adapted to close the bottom of a cylindrical receptacle to retain the material which has been cut thereby within the re ceptacle.

A further object of the invention is to provide a well auger in which the receptacle may be emptied of its contents when the device has been removed from the well.

A further object of the invention is to provide a well auger in which the cutting element is operated automatically to prevent discharge of material from the cylinder upon the withdrawal of the device from the well.

Referring to the drawings:

Figure 1 is a vertical sectional view showing the auger in its operative position.

Fig. 2 is a vertical sectional view showing the cutting member in its closed position.

Fig. 3 is a bottom view, an

Fig. e is a perspective view of the blank from which the cylindrical receptacle is formed.

Referring more specically to the drawings the device comprises a cylindrical casing 1 formed of sheet metal, and extending across the upper end of the cylinder' is a bar ffl which is preferably of cast metal and is provided with a central squared opening 3, the purpose of which will be hereinafter set forth.

As shown in Fig. 3 a bar 4 extends across the lower end of the cylinder. said bar 4 being arranged in a plane at right angles to the rst mentioned bar 2 thus aiding in bracing the cylinder.

Extending upwardly from the bar 4 is a standard 5, this standard 5 being arranged centrally of the cylindrical casing 1, and passing through the squared opening 3 of the bar 2 is a squared rod 6, the lower extremity of which is provided with a recess 7 which extends longitudinally thereof and is adapted to receive the vertical standard 5.

Pivotally connected to the bar 6 as by means of the collar 8 is a link 9, said link extending downwardly through the bottom of the cylindrical member and is connected to a cutting element 10 by means of a nut 11 as shown in Fig. 3.

This cutting element 10 is hinged as at 12 to a stationary portion 14 of the bottom to permit of a vertical movement thereof to close the bottom of the cylindrical member during the operation of removing the device from the well thus preventing the discharge of any material within the cylindrical member.

Hinged to the transverse brace t is a semicircular disk 14 which is secured thereto by means of the hinges 15, said disk 1li being maintained in its closed position by means of a suitable latch 16.

As shown in Fig. 4, the blank from which the cylindrical member 1 is formed comprises a substantially rectangular sheet of metal, the lower edge of which is cut away as at 17, and it will be seen that when the edges of the ends of this blank are brought together to form the cylindrical member a depending portion 18 is provided on' the lower edge thereof, and it is within this depending portion that the cutting member 10 is adapted to move when not in opera` tion.

From the foregoing it will be seen that when the device is inserted into an opening in the ground and rotary movement given to the squared shaft 6, the cylindrical member 1 will be rotated and will carry with it the cutting member 10 which owing to the vertical thrust on the squared shaft 6 and its link connection therewith will be projected as shown to perform the cutting operation. vVhem however, the cylindrical member -1 has become filled to the desired amount with material severed bv the cutting` member l0, the same is withdrawn from the opening by pulling vertically on the squared shaft 6 and it will be seen that during this withdrawing action the link 9 operates to move the cutting member 10 within the bottom of the cylindrical member thus closing the bottom thereof and preventing discharge of the material contained therein. IIltis operation is permitted by reason of the sliding engagement between the recess 7 in the lower extremity ot the ysquared shaft 6 With `the vertically Jextend-v ing member 5 hereinbefore described. When the device has been entirely removed from theopening, the latch member 16 may be operated to permit of the semi-circular bot# tom 14 swinging on its-.hinges to entirely discharge the contents of the cylindrical member. v

Having thus described the invention,v what is claimed is ,1. A device of the character described, comprising a cylindrical casing, means for closing a portion of the .bottom ofsaidvcasing, means for rotatingsaid ycylindrical casing, and a .cutting element Aconnected to said casing rotating means `and adapted `to close the remainder of the bottom of the cylindricalcasing.

:2. A device of the character described comprising .a cylindrical casing, means `tor closing a portion of the bottom fofsaid casing, :means Afor rotating the casing, ahinged 4cutter vcarried :by the bottom of the :casing .and adapted 'to close the open portion thereof, and means connecting` vthe hin-ged cutter with the casing :rotatingmeans y.to operlate said cutter.

3. A device of the character described comprising a cylindrical casing, means for closing a portion of the bottom of said cylindrical Vcasi-ng, a hinged cutting member secured to the bottom of the casing adjacent the open portion. thereof, means for rotating the casing and adapted tor vertical movement Within the casing, vand vineans `connecting said hinged cutter and same, and a link connecting the casing ro- L tating means and said pivoted critter to move the cutter .about its 4pivot to close the open portion of the bottom upon vertical movement of the 'casi-ng rotating means.

In testimony whereof, I aflix my signature, in the presence of tvvo Witnesses.
